Application filed March 5, 1912.

1 (1 UN. w/wm. vzmg com-cm Be it known that l, lVAL'rEn S. lll on'ron, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsyl 'ania, have invented certain new and useful Improvements in Spokelighteners; and I do declare the following to be a full, clear, and exact descriptirm of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

'l his invention relates to carriages and wagons, and more especially to that class of devices therein known as spoke sockets; and the object oi the same is to produce an extremely cheap device of this kind applicable to most any form 01" rim and spoke and by means of which the latter can-be" instantly tightened when it becomes loose.

To this end the invention consists in the details of construction hereinafter more fully described and claimed, and as shown in the drawings wherein Figure l is a side elevation of a portion of the rim, three spokes, and the interposed tightencrs. Fig. 2 is an enlarged central vertical section through the parts of one of my improved tightcncrs, taken in the central plane of the wheel, and Fig. 3 a similar section at right angles thereto on the ine of Fig. 2. Fig. 4C is a detail sectional View similar to 2. showingonly the two members of the spoke tightener slightly separated from each other Fig. 5 is a perspective detail of the two inen'ibers slightly separated.

In the drawings the letter R designates the rim. licrc shown as oi sheet metal and its construction forms no part of the present invention; and the letter S designates a spoke, here shown as round'and solid although its detailed construction and its material form no part of the present invent ion. \Vhcrc these elements connect with each other there is usually interposed a device known as a spoke socket, and the purpose of the present ii'nention is to produce an extremely cheap andscrviceable art cle of this character aswill. now be described.

The outer member has a preferably rec tangular body 1 curved along its outer Specification of Letters Patent.

extending from the sides oi said body, prer erably near its ends and out of alinement with each other as shown, and through which pass rivets or bolts a by 'ineans which the device is connected Witlrthe' rim, 6G The inner face of said body is cutoff j oblique so that at one end said cup is rather shallow and at the other it is ratli'eri deeplj its deeper end standing inside an enema 5 whose extremities are continued asa into sidewalls of triangular contour teri nating in shoulders 7 near the other 'endof the body. The bottom of the cup is term d by preference inclined and which excendsfle across the interior of the body a, littleaboV'e-f the lower edges of the end and sidewalls so" that such lower edges form flangeslexten ingaround three sides of the Web 8. Finally, a a hole 9 is formed through the end wall 5 and the web 8 on a line strictly parallel 1 h j the length of this member fora purpose to] appear below. The inner member has a body whiclitisi substantially triangular in side eleiiatio ilsfi as seen at 11, its narrower end 12being flan" tened to make contact with the edge gra e end wall 5, and its Wider end havi.i1gali .p

13 so spaced from said narrower end that it,- will sin'mltaneously make contact with the: B shoulder 7 above referred to; and the Width of this body is such that it may move freely between the side flanges of the outer memher when its inclined face rests upon the inclined face of the Web S. This member also pierced with a longitudinal hole 14: opening through its lip 13, standing parallel with its fiat inner face, running out through its oblique face, and preferably made slightly OYjtl for a purpose to appear below. Connectinp; said two members is an ordinary bolt 15 having a head 16 at one end and a nut 17 threaded onto its other end, and the same is preferably inserted so that the head shall stand against. the larger end or lip l of the inner member, while the shank eX- tends loosely through the hole 14itherein and then through the hole in the outer member, and the nut is screwed upon the projecting end of the shank and against the end wall 5 of said last-named member The spoke S is attached to the inner member in any suitable way, as by forn'iing said member with a recess 18 in its-inner tan into which the outer end of the spoke is n Patented Feb. it,

serted, and the means for holding it thereif any be employed-atoms: no essential .part of the present invention.

lVith the parts of my device constructed in their preferred form as above described, they will doubtless be made of metal cast.-

ing or-forging, but it is not impossible to 'stamp' one or both members from sheet .is secured or inserted within the socket in an inner member; then the beveledi'ace of the latter is placed within the recess formed by the three walls of the inner side of the outer member and upon its web 8, and'the will .be clean because in the sliding movemnt of one menr' i-ber on the other holesin them which were truly round would be thrown out of register. When the adjustment has been carried. to

bolt inserted; and when it becomes desirable to tighten this spoke, it is but necessary to set up the nut on this bolt in a manner which Tllls action draws the inner 5 member alone inside the outer member so that their inclined faces more over each other, and the desirability of making the hole 14 slightly oval will now be apparent such an extent that the lip 13 of the inner member comes up against the shoulder 7 of. -the outer and no further adjustment is therefore possible, the parts will be loosened and 'a shim or washer inserted over the end of the spoke, either at its inner extremity or its outer extremity, after which the operation What is claimed as new is:

above described may be repeater.

1', The herein described spoke tightener, the same comprising an outer member consisting of side and end walls laterally disposed non-registering lugs pierced with holes for the assage of means to attach the device to t e rim,"and an internal oblique web, said end wall being provided with a hole opening through said oblique web; and an innermember whose body is substantially triangular in side elevation and of a width to fit between the side walls of the outer member, and whose thicker end has a lip projecting beyond its oblique face, there being'an oval hole through said lip and face; and a bolt passing through said holes, for the purpose set forth.

2. The herein described spoke tightener,

the same comprising an outer member ob-' lique on its inner side and curved on its outer side to conform-with the curvature of the interior of the rim and cupped in this.

side for sake of lightness, the member consisting of end walls, side walls having lateral lugs "pierced with holes for the passage of means to attach the device to the rim, and

an internal oblique web, said end wall beingprovided with a hole opening through said web; and an inner member whose body is substantially triangular in side elevation and of a width to fit bctii'eelithe side walls of the outer member, and has a lip projecb.

ing from the thicker end thereof beyond its oblique face and adapted to contact With the thinner end of said first-named member when the thinner end of the inner member contacts with the end wall thereof, there being a hole through said lip and face; and a bolt passing through said holes, for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- WALTER s. MORTON. lVitnesses.
